Firefox 115.3.1

I updated Firefox to 115.3.1esr (windows 8.1 64 bit).

I noticed a dramatic drop in performance on my code that I know worked fine on Firefox and Chrome.

Can you run this program in Firefox and tell me if it works fast (the graphics should be generated within a few seconds - max 15 seconds).

Please write in this thread what version of Firefox you use.

If generation is very slow (it takes minutes to generate graphics). Then you can do another test and run another test program

1. Go to these two links and tell me if you see graphic glitch in the "sprites" section (blinking sprits, changing sprits when you point the mouse at them).
2. when running the program, you saw graphical glitches (the entire image flashing, sprite textures displayed on the screen)
3. You had artifacts while watching YouTube.

I want to send a report to Mozilla and I need some more systems with the same error.

Firefox 118.0.2 (64-bit) running on Windows 10 on an excuse of a desktop box PC, lol.
All running as expected. Sure that it is Firefox related, works fine on Chrome? Also, I see they stopped support for Windows 8.1 like so many others, might be time to upgrade :(
